Uplink vs Downlink | difference between Uplink and Downlink

This page compares Uplink vs Downlink and mentions difference between Uplink and Downlink.

Uplink

The frequency used for all the transmissions from Mobile Subscriber Unit (MS) to the Base Station (BS) (i.e. Node-B, eNB) is known as uplink frequency. This direction from MS to BS is called uplink direction.

Uplink Example#1 (VSAT): 5925 MHz to 6425 MHz for C Band, Refer VSAT System Overview>>.

Uplink Example#2 (GSM): 890 MHz to 915 MHz, Refer GSM system tutorial>>.

Uplink vs Downlink

Downlink

The frequency used for all the transmissions from Base Station to the Mobile Subscriber Unit (MS) is known as downlink frequency. This direction from BS to MSs is called downlink direction.

TDD and FDD is used in combination with FDMA and TDMA in order to use the bandwidth effectively.

Downlink Example#1 (VSAT): 3700 MHz to 4200 MHz for C Band

Downlink Example#2 (GSM): 935 MHz to 960 MHz
